key is not certified with a trusted signature!

[rovernut]

My apologies if this is a double post. I tried to post it once before and it appears to never have made it, or maybe it's awaiting approval since it's my first post.

I searched the forum via google for my problem and found two threads, neither of which gave a solution, so....

I downloaded kali-linux-2.0-amd64.iso from https://www.kali.org/downloads/
I then downloaded SHA1SUMS and SHA1SUMS.gpg from http://cdimage.kali.org/kali-2.0/

Running as user I ran

wget -q -O - https://www.kali.org/archive-key.asc | gpg --import

and got

gpg: key 7D8D0BF6: "Kali Linux Repository <[email protected]>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1

(I'd run it already once before)

Then I ran

gpg --verify SHA1SUMS.gpg SHA1SUMS

and got this

gpg: Signature made Tue 11 Aug 2015 09:35:26 AM EDT using RSA key ID 7D8D0BF6
gpg: Good signature from "Kali Linux Repository <[email protected]>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 44C6 513A 8E4F B3D3 0875  F758 ED44 4FF0 7D8D 0BF6

Is the uncertified signature warning a known bug, or something I need to be concerned about?

Thanks

Same issue tried a number of loaders and various versions of kali linux from this site. Help please. Trying to load from a live usb

I don't know why google didn't pick up more threads, but when I went to the "Search Kali Linux" page it found others with This key is not certified with a trusted signature! in them.
One of them had the answer. Here's the relevant snippet.

the 3rd line appears because you haven't got the public key from the signer but we now that it is the signer by matching the fingerprint to the one on kali's site if you wanted to you can email the key owner and get the public key from him and import it in by emailing him at [email protected] but it's always better to get keys in person....

So I did a "cat SHA1SUMS" and compared the hash for kali-linux-2.0-amd64.iso to the one on this page https://www.kali.org/downloads/

They match, so I'm good to go.

I am very wet behind the ears when it comes to pen testing and open source in general but it seemed to me if I abide by the principle of "assume NOTHING" I'll probably eventually understand it all.

In that spirit I have experienced the same problem trying to verify the kali 2.0 torrent I downloaded and I couldn't help but notice there is one extra white space character in the fingerprint between 0875 and F758 than is indicated at the official kali download page (https://www.kali.org/downloads/).

99% of me says that is not meaningful but I know very little and assume nothing - can someone clarify for me?
